Final answer:
In the equation 52 = 15·3 + 7, the number 7 is the remainder.
Step-by-step explanation:
In the sentence 52 = 15·3 + 7, 7 is the remainder.
To understand why, we need to break down the equation.
We start with the number 52, which we can express as the sum of two parts: 15·3 and 7.
The term 15·3 represents a multiple of 15, which is 45, multiplied by 3.
So, we have 45 + 7, which gives us a total of 52.
The remainder is the number left over after grouping the multiples together, in this case, the number 7.
